Which payroll systems have GL mapping and custom file formats?

TL;DR

GL mapping works best when payroll data is structured and consistent so each pay element and cost centre posts to the right account. This guide explains the mapping approach and file formats that reduce reconciliation work.

“Which payroll systems have GL mapping and custom file formats?” It’s a question payroll and finance managers across Australia and New Zealand ask every month-end, usually while wrestling with a GL export that won’t play nicely with their ERP.

If you’ve ever had to reformat columns, fix account codes, or wonder why credits don’t match debits, you know how costly these limitations can be. The truth is, most payroll systems were never built with the finance team’s needs in mind – and that’s where the trouble starts.

Why is GL mapping so frustrating?

GL mapping is frustrating because most payroll exports are generic, inflexible, and require manual rework to meet finance requirements.

  • Generic exports that don’t match your finance system’s requirements.
  • No way to separate GL account mapping from employee costing.
  • No GL groups to post specific payroll elements differently.
  • Missing balancing checks, so errors slip through until month-end reconciliation.
  • Endless manual manipulation just to get the file into your ERP (SAP, Oracle, TechnologyOne, MYOB Advanced).

Why does GL mapping accuracy matter?

It matters because finance relies on payroll output to close the books, and mismapped data slows month-end and creates errors.

  • Month-end close takes longer
  • Posting errors creep in
  • Reconciliations become a fire drill
  • Finance loses trust in payroll numbers

In large enterprises with multiple entities, cost centres, and complex awards, the stakes are even higher – and the margin for error is slim.

GL mapping FAQs

What is GL mapping in payroll?

GL mapping assigns payroll entries to the correct ledger accounts and cost centres. It ensures payroll results post cleanly into finance systems.

Why do payroll exports often fail in ERPs?

Many exports are generic and do not match ERP formats or account structures. This forces manual reformatting and increases reconciliation errors.

Do I need separate mappings for costing and GL?

Yes, separating costing from GL posting improves flexibility. It lets finance and payroll track the same pay data in different structures.

How do custom file formats help?

Custom formats match ERP import requirements exactly. That reduces manual edits and speeds up month-end close.

The future you can have

Your GL file drops straight into your finance system – balanced, accurate, and detailed. Your month-end close is faster. Your CFO trusts payroll numbers without question.
